Just when I thought my Belton tube sockets look good, you come and do this... ::) Damn, it looks excellent! That is just fabulous work.

Looks like you used the Tube Depot terminal strips on the transformer. How easy was it to bend them into position like this? Mine seemed to be close to breaking, so I cut away some of the screw holes to mount them. They still ground perfectly, but it is not the perfect solution since they can move unless they are seriously tightened down.

Interesting mounting of the rectifier pcb. Based on your post on richmi's thread (http://bottlehead.com/smf/index.php?topic=7215.msg74585#msg74585), I am assuming you merely used some 18/20 awg wire to hold them in place. How sturdy is that and aren't you afraid of shorting out the transformer?

Final question, what capacitor are you using for the final PS cap? Looks like a Dayton, but I can't make out the capacitor values?
 
Well that just makes me want to go and build another Crack and try out some of those mods the Mundorfs fit a treat and is that some kind of gear assembly you have utilised round the socket?

 
Lee,

I just noticed the bubble gum on the hot and neutral of the IEC connector.  I use RTV often for insulation.

-The terminal strips are not from Tube Depot, they look similar but I have had these for years and mine look like they have thicker bakelite, the terminals are sturdier than the bottlehead strips and this is the only reason why I use them

-I have found that if you need to cut the mounting holes it is better to use the stock bottlehead strips

-The PCB is extremely sturdy with just the wire, but I did remove two terminals for clearance

-The output cap is a Dayton 100uf 250v

-The Mundorf Caps made for an easy installation, it sounds really good, to me using a standoff just adds an unnecessary solder joint, I do not like the sound of solder  ;)

-It is an old IBM computer fan heat sink with an in house machined brass tube socket "holder",  The heat sink does work extremely well

-Granger the pink bubble gum is gas line teflon tape, much thicker than normal white teflon tape
